I've basically got the total MP3 setup in my Protege5. MP3 ECU, 4-2-1 headers, hi-flow cat, CAI, 9lbs flywheel, RR Racing UDP, big port work on the head and intake manifold.
125whp---126wtq. Mustang dyno.
The porting on the head and manifold seem to make a big difference compared to other similar setups that don't have it. My next big HP mod will be a set of adjustable cam gears and to actually tune my MPI piggyback. I'm hoping to get over 135whp with that setup.
